The main issue is if The Hammonds wanted the seige to occur and for the Bundy Brothers to be come to Oregon. Many people claim they didn’t support them.
The Hammonds have been threatened with further prosecution for not paying the full $400,000 fine by the end of 2015. The fine was levied as part of original sentencing and it's a crime to not pay it on time. Another felony.
I'm pretty sure the Feds and the Hammonds are both happy to call it even (they've already paid $200,000) if the Hammonds don't publicly call for help.
